lithium metal x-ray refractive lens

Ecopulse has successfully applied lithium metal to x-ray windows thanks in part tomethods to delay its corrosion in air. This project is to use lithium's high x-raytransparency to refractive lenses. To date these are made from aluminum, plastics andberyllium. Lithium promises a refractive x-ray lens with larger aperture, smallerfocal spot, and higher peak intensity than these traditional materials, and allowsthe useful photon range to be extended to softer x-rays than the optimum 10 keV.Lithium lenses should enhance the various capabilites of synchrotron (and other)x-ray sources. For example, the smaller, more intense x-ray spot created by the lenscan examine advanced electronic or structural materials over smaller areas and in ashorter time. The lens can similarly improve standard laboratory x-ray sources.such as the Advanced Photon Source
